The number of tyrosine hydroxylase positive cells (TH⁺ cells) in the left (L) and right (R) brain hemisphere at the bregma level: −4,80 mm, −5,20 mm −6,04 mm in the deep brain subthalamic nucleus stimulated rats with PD model (DBS-6OHDA group, n = 14), non-stimulated rats with PD model (6OHDA group, n = 9), control (SHAM group, n = 14) group and representative photomicrographs of brain coronal sections (−5.20 mm) for rats in each group. Explanations: ***p ≤ 0.001 – difference vs. left hemisphere of DBS-6OHDA group; ###p ≤ 0.001 difference vs. left hemisphere of 6OHDA group, $$$p ≤ 0.001 difference vs. left hemisphere of SHAM group; @@@p ≤ 0.001 difference vs. right hemisphere of SHAM group; Tukey’s HSD post hoc after two-way ANOVA
